a MASSAGING DEVICE,

) Application filed .Tune 23, 1919. Serial No. 306,087.

To all whom it may concern:

Be it known that I, FREDERICK HOWARD AULD, a citizen of the United States, residing at Columbus, in the county of Franklin and State of @hio, have invented a certain new and useful Improvement in Massaging Devices, of which the following is a specification.

This invention relates more particularly to the type of massaging device shown in the United States patent to Siebert No.

1,001,175, Aug. 22, 1911. Such devices are expensive to manufacture because it is necessary to bore the cylinder to provide a proper fit for the piston. The object of the present invention is to avoid this expense and also to make it easier to clean the device. The invention is embodied in the example herein illustrated, described and finally claimed.

In the accompanying drawing- Figure 1 is mainly a central vertical section.

Fig. 2 is a top plan view.

In the views 5 designates a chamber, having its lower end closed and its upper end internally threaded to receive the head 6. The head 6 has an extension 7 provided with a socket having a packing 8 to receive a removable cup 9.

10 designates the piston having a rod 11 extending through the head 6, said rod being provided with a finger piece 11. In the present instance the head is provided with a cylinder of glass 12 in which the piston works. Said cylinder can be a piece of ordinary glass tubing uncovered at its lower end and cemented at its upper end in a suitable recess in the lower side of the head 6. The cylinder should be of such length as to not quite reach the bottom of the chamber 5 so that air from the chamber and from the cup can be drawn by the operation of the piston. The piston is operated in the upward direction by a spring 13, said spring in the uncompressed state being of about the length of the cylinder and pressing on the bottom of the outer chamber. A hole 14 affords the passage for the air from the cup to the chamber beyond the glass cylinder.

In practice the user pushes the plunger down and places the cup against the face or other surface of the body to he massaged and moves the cup about as usual in the massaging process. Upon the release oi? the piston the pressure of the spring creates a partial vacuum in the cup with the effect of drawing up the skin as usual in instruments of this type.

With the cylinder, as herein provided, the device is economically constructed and the parts easily separated for cleaning.

What I claim is:

A massaging device comprising, in combination, an exterior vessel, a removable head directly connected with the vessel for air tightly closing the same, a cylinder within the vessel attached at its upper end to said head and open at its lower end, said cylinder removable from the vessel with the head, a piston for said cylinder having an operating stem extending through said head with an air excluding t, a spring in said cylinder compressible by the piston against the bottom of the exterior vessel, and a vacuum cup carried by said head having a passage communicating with the vessel for both the intake and exit of air therefrom.
